QUESTION Which of the following is the first step in the transmission of signals at a chemical synapse? Calcium channels open Calcium comes into the presynaptic cell Neurotransmitters are released Neurotransmitters bind to postsynaptic receptors QUESTION Which of the following describes electrical synapses, but not chemical synapses? Neurotransmitters are released from the presynaptic cell The action potential in the presynaptic cell results in the opening of calcium channels Gap junctions open to send the electrical signal directly to the QUESTION Which of the following does not happen after a neurotransmitter binds to a postsynaptic receptor? The neurotransmitter may be recycled. The neurotransmitter may be degraded The neurotransmitter may enter the postsynaptic cell. The neurotransmitter may diffuse away from the synapse.
